From 8a19b8f19429b86c91e10745bc131bc600e60ede Mon Sep 17 00:00:00 2001 From: Andrew Bresticker Date: Thu, 18 Sep 2014 14:47:19 -0700 Subject: [PATCH] MIPS: Move GIC to drivers/irqchip/ Move GIC irqchip support to drivers/irqchip/ and rename the Kconfig option from IRQ_GIC to MIPS_GIC to avoid confusion with the ARM GIC.
